JAMES J. HENNESSY, OF NEW YORK, N. Y.

JOURNAL nnnnrcnron.

Application filed. September 20, 1921. Serial No. 501,866;

To all whom it may concern:

Be it known that 1, JAMES J. HnNNnssY, a citizen of the United States, residing at New York city, New York, have inventeda certain new and useful Improvement in Journal Lubricators, of which the following is a full, clear, and exact description, such as will enable others skilled in the artto nism whereby the lubricant is "fed from the lubricator reservoir to the journal assembled with the lubricator.

One object or my invention is to provide a simple pump operating mechanism. adapted to be actuated by the vertical movement of the journal and lubricator relative to the frame of the truck.

Another object of my invention is to provide a lubricator especially adapted for use on a locomotive and to be actuated by vertical movement of the locomotive pedestal binder relative to the journal and lubr1- cator.

In the accompanying drawings, which illustrate a selected embodiment of my invention Figure 1 is a longitudinal section through my improved lubricator showing the locomotive journal and pedestal binder in dot and dash lines.

Figure 2 is a transverse section through a lubricator on line 2-2 of Figure 1 with the accompanying locomotive parts indicated.

The lower portion of the body 1 of the lubricator forms a reservoir for the lubricant which may be supplied therethrough through a filling plug 2. A waste pan 8 is supported within the lubricator with its bottom spaced substantially from the bottom of the well. Positioned centrally of the lubricator and extending upwardly from the well to a point adjacent the bottom of the journal is a hollow cylinder 4 forming the barrel of a pump, the lower portion of which is open to the well. Mounted in barrel 4 is the pump plunger 5 which is rovided with laterally extending arms 6. arrel 1 is slotted at 7 to receive the arms 6 of the plunger. It will be noted that slots 7 are located a substantial distance from the bottom of the well,in tact, being above the bottom of the waste pan 3.

An integral lug 8 is formed on barrel 4: and a lever 9 is iulcrumed on lug 8 at 10. One end of lever 9 is forked to engage arms 6 projecting through each side of barrel 4.

Adjacent to barrel 4, I provide a'boss 11 on the bottom of the reservoir which extends upwardly to a pointbeyond the bottom of waste pan 3 and above the normal level of lubricant in the reservoir. A vertical passage through boss 11 accommodates an operating rod 12 which has a sliding fit llltl'llS opening. The upper end of arm 12 is pivot-- ally connected to the unforked end of lever 9 and the opposite end extends downwardly below the outside bottom of the reservoir and is adapted "to contact with the pedestal binder of a locomotive on which the lubricatoris mounted.

A spring 18 is compressed between the bottom of the reservoir and a shoulder 14 on rod 12. Preferably the bottom of the reservoir is recessed at 15 to accommodate a more efficient spring.

It will be seen that when a wheel mounted on the journal strikes an obstruction or the swaying of the locomotive body causes a relative movement between the lubricator and the pedestal either the action of the spring 13 or the contact of rod 12 with the pedestal binder will shift the rod vertically and through lever 9 operate the pump plunger. The reciprocal action of rod 12 produces a corresponding reciprocal action of plunger 5 which intermittently forces the lubricant from the well to the top ofbarrel 4, from whence it spreads along the journal to the sides and intermediate portions thereof. Any surplus oil will be stored in the waste up to the limit of absorption of the latter and any additional lubricant will find its way back to the well and be again pumped therefrom as required.

It will be noted that the bottom of pan 3 is recessed at 16 to receive the pump barrel and the plunger operating mechanism, keeping the latter tree from waste packed in the pan. Compression springs 17 yieldingly support the pan against the journal and take up any wear or compression.

I am aware that many modifications may be made in the details of construction of my invention and I contemplate such changes Ila" in the commercial development, without departing from the spirit or the invention, as claimed.

I claim:

1. In a journal lubricator, a lubricant reservoir, a pump for elevating lubricant from said reservoir to a journal, and a pump operating member extending throu h the bottom of said reservoir.

2. In a journal lubricator, a lubricant reservoir, a pump for elevating lubricant from said reservoir to journal, including a pump plunger, a vertically reciprocating member extending through the bottom of said reservoir, and a lever iulcrumed to a fixed point in the lubricator and having its opposite ends pivotally connected to said member and to said plunger respectively.

i In a journal lubricator, a lubricant reservoir, an upstanding boss in said reser voir, a passage from the top of said boss to the outside of the bottom of the reservoir, a rod slidably mounted in said passage, a pump mechanism for elevating lubricant from said reservoir to a. journal, and means connecting said rod and said pump mechanism for operation or the latter by external actuation of said rod.

t. In a journal lubricator, a lubricant reservoir, a waste pan spaced from the bottom of said reservoir, a pump cylinder extending from the bottom of said reservoir to a point adjacent to the top of said pan, a pump plunger in said cylinder, a boss on the bottom of said reservoir extending upwardly to a point above the bottom of said waste pan, a vertical opening through said boss, a rod reciprocally mounted in said opening, and a connection between said plunger and rod, whereby movement of the latter operates said. plunger to raise lubricant through said cylinder.

5. In a journal lubricator, a lubricant reservoir, an upstanding hollow cylinder provided with a passa e to the lower portion of said reservoir, with slots in its sides and with an integral fulcrum lug, a plunger in said cylinder provided with arms extending through said slots, a lever fulcrumed on said lug and having one end engaging said arms, and a reciprocal operating rod extending exteriorly of the reservoir and connected to the other end of said lever.

6. In a journal lubricator, a lubricant reservoir, an upwardly extending pump barrel, a plunger, a plunger operating mechanism positioned adjacent to said barrel, below the top thereof and extending downwardly therefrom, and a pan for containing waste packing spaced from the bottom of said reservoir and from said barrel and operating mechanism.

7. In a journal lubricator, a lubricant reservoir, an upwardly extending pump barrel, a plunger, a plunger operating mechanism positioned adjacent to said barrel and below thetop thereof and extending downwardly exteriorly of said reservoir, and a waste pan spaced from the bottom of said reservoir having a recess in its outer bottom "face surrounding said barrel and mechanism.

In testimony whereof I hereunto aifix my signature this 29th day of June, 1921.
